(Cl. 1Z0-'29) This invention relates `to-copyholders, and more particularly to copyholders of the -typewhich'may be readily collapsed.

The primary object of the present invention is to provide an 4improvedcopyholder which -mayf vfor the copyholding member which is jointly caryried-by the-base andcarrier with interconnecting vmeans permitting thecarrier to-be readily moved to its collapsed position.

A still further object of the present invention is to provide acopyholder of the above-type having means for returning the copyholdingmember Ato ts'normal position on the carrier as the carrier is moved toits collapsed position.

To the above and other ends whichwill-hereinafter appear, theinventionconsists in the features of construction, arrangements ofparts, and combinations of devices set forth inlthe followingdescription and particularly pointed out in the appended claims.

The particular copyholder to which the invenftionIhas-been appliedlinthepresentinstance-is 0f the type wherein the copy sheets are-securedtoa rcopyholding member and are intermittently .movedlpast a stationarylineindicator. InA this type of4 copyholder, the copyholdingmember-andvlineifndicator are necessarily positionedwhenin vusea considerabledistance above the topofan ordinary typewriter, and the usual.foldingcabinet in a typewriter-desk will notr accommodate thecopyholding member whenin such raisedv position. Accordingly, thecopyholding member andline indicatorare mountedin .the present instanceon a carrier which mayfbe movedrelative to the base from araisedoperative position to a `lowered collapsed position which permits Athecopyholder to behoused along. with a ltypewriter inthe folding Ycab-inetof a typewriter desk.

IThe support or base for the copyholdercomprisesan Llshaped structureformed by va rear base member I0 and .a forwardly extendingfbase vmemberII as showninFig-8. When the present copyholder is positionedfor'u-sewitha .type- .writing machine, such. as ythe machine Tv shown.in Fig, .1, the rear base member I'U isfdisposed along vthe-rear sideof.the machine and `the forwardly extendingbase member II is fdisposedalongthe right .hand side thereof. .This L-shaped base structure forthe-copyholder is supported on the same surfaceas the typewritingmachinev T by three rubber feet I2 carried by 4the rear base member I0as shown in Fig. 8 and a similar rub- ;ber foot I3 carried by the'forward end of the' base member I I as shown in Fig. 1.

In order to occupy lessspace when being stored v or shipped, theforwardly extending base member Il .is adapted to be folded against therear. base Thus, the forwardly extending base member IfI' is pivotallyconnected to the rear. base member I0 by a bifurcated bracket I5 securedto .the'base member 'I I, whichbracket is connected by a pivotscrew I6to a bracket Il securedto the rear base member I0 as shown in Figs. 2, 7and 8.

The basemember II may thus be moved about the axis of the pivot screw I6to a foldedp'osition against the front side of the base member I0, andwhen the basemember II is in its forward operative position as shown,the lower'end of --a spring pressed detent plunger I8 (see Fig 2) entersa detent hole provided inthe base member IIJ to resiliently hold thebase memberY II in a position extending substantially at right-anglev'tothe base memberv I0.

'Ihe copyholding parts of the present construction are mounted on acarrier which is in turn mounted for movement relative to the basebetween a lowered collapsed position and a raised operative position aspreviously pointed out. This carrier comprises a rear sheet metal platewhich is mounted for vertical movement on a pair of spaced guide posts22 which are fixed at their lower end to the rear base member Ill. Thecarrier plate 20 is provided with lateral extensions 23 at the lower endthereof which are curved to partially embrace their respective posts 22,and associated retaining pieces 24 are secured to the inner surface ofthe plate 25. These retaining pieces are likewise curved to partiallyembrace the opposite portions of the posts 22 as shown in Figs. 2 and 7.The carrier plate 20 is thus mounted to move on the guide post 22between its lowered collapsed position shown in Fig. 1 and its raisedoperative position shown in Fig, 2.

Releasable latching means are provided for holding the carrier plate 20in its operative position, and comprise a pair of latches 26 which arepivotally mounted on respective shouldered screws 21 carried by theplate 26. The screws 21 are retained by associated nuts 23 as shown inFig. 6, and the latches 26 are spaced inwardly from the carrier plate 20by associated collars 29. Each of the latches 26 is provided with aninwardly extending arm which is pvotally connected to the lower end of acompanion oifset link 3D. The upper end of each of the links 3@ ispivotally connected to the inwardly extending end of a companion latchreleasing lever 53 pivotally mounted at 34 on the inner surface of thecarrier plate 20. Springs 36 exert a downward pressure on each of thelinks 35 to resiliently hold each of the latches 26 in a positionwherein a forwardly extending lug at the lower end of each of thelatches engages a shoulder 31 formed by an annular groove at the upperend of each of the guide posts 22.

The latches 26 are thus effective to normally hold the carrier in itsraised operative position on the guide posts 22. The outer end of eachof the latch releasing levers 33 is providedwith an offset finger piece40 shown more particularly in Fig. 6, and the carrier may be readilymoved to its lower position by pressing downwardly on each of the fingerpieces 4D to move the lower end of the latches 26 clear of the shoulders31 against the force of the spring 35. In order to facilitate theraising and lowering of the carrier, a pair of arms 42 are fixedlysecured at 43 to the carrier plate 20. These arms i2 are positioneddirectly beneath the respective latch releasing levers 33, and the arms42 are provided with respective offset nger pieces 44 which aregenerally the same shape as the finger pieces 46 but reversely disposed.When the carrier is raised to its operative position with the aid of thearms 42, the lower ends of the latches 26 slide along the insides of theguide posts 22 and move outwardly under the force of the springs 36 whenthe carrier reaches its fully raised position to retain such position byengagement with the shoulders 31. A stop arm 46 is secured by acompanion screw 41 at the upper end of each of lthe guide posts 22, andthese stop arms are engaged by the nuts 23 to limit the upper movementof the carrier.

The top and bottom edges of the carrier plate 20 are bent forward toform flanges as shown in Figs. 3 and 4, and a front cover plate 50 ispro- 75 vided with rearwardly extending top and bottom flanges whichoverlap these forwardly extending top and bottom portions of the rearcarrier plate 26. A pair of vertical guide rods 52 are mounted in spacedparallel relation between the rear carrier plate 29 and the cover plate5, and screws 53 pass through openings in the top and bottom flanges ofthe plate 20 and cover 5U, which screws are threaded into the ends ofthe guide rods 52 to hold these parts of the carrier in their assembledrelation.

In the present copyholder, the copy sheets are moved with relation to aline finder or indicator mounted on the carrier as previously described.However, from the broader aspects of the present invention, it is to beunderstood that the copy sheets could be mounted stationary on thecarrier and the line indicator could be arranged to be moved withrelation thereto.

The specific form of line indicator shown in the present drawingscomprises a horizontally disposed strip 55 shown particularly in Figs.1, 3 and 4. The strip 55 is shown as being of sheet metal, but it may befound preferable to use a semi-transparent or translucent material suchas colored Celluloid. The lower edge of the strip 55 is suitablyattached to a horizontally disposed bail rod 56 and in the presentinstance, the lower edge of the strip 55 is benl-I around the rod 56 ina manner to permit the strip 55 to be adjustably turned about the rodbut to grip the rod with suflcient tension to retain its adjustedposition thereon. The ends of the bail rod 56 are bent downward and theninward as shown in Figs. 1 and 2. The inwardly extending ends of the rod55 are frictionally retained in sockets formed in brackets 51 byclamping members 56 secured to the respective brackets by screws 59. Thebrackets 51 are secured at 66 to the inside surface of the carrier plate26. The screws 59 are adjusted to grip the lower ends of the rod 56 withsufcient tension to allow the bail rod to be adjusted to obtain thedesired position of the line indicator and to frictionally hold it inthe adjusted position.

The means for advancing the copy sheet past the line indicating strip 55is shown in the accompanying drawings as a copyholding member 65 mountedfor bodily movement relative to the carrier. However, it is to beunderstood that from the broader aspects of the present invention, otherwell known means may be employed for moving the copy sheet with relationto the carrier and line indicator. For example, a roller feedingmechanism of various types well known in the art could be employed forthis purpose.

The copyholding member 65 in the present in- .stance is in the form of arectangular sheet metal plate which is reinforced by rearwardly bentflanged portions around its edges. The copyholding plate 65 is mountedfor vertical movement on the guide rods 52 by a bracket 66 secured toits rear surface at the lower end portion thereof. Referring to Figs. 3and 4, it may be seen that each end of the bracket 66 is provided withtwo rearwardly extending ear portions in vertically spaced relation.These ear portions of the bracket 66 are provided with eyelets 61 whichreceive the guide rods 52, whereby the copyholding plate 65 is mountedto move freely along the vertical guide rods. As may be seen in Figs. 2,4, 6 and '1, the inwardly extending ears on the brackets 56 pass throughthe respective vertically disposed slots 68 in the carrier cover plate50 to permit the copyholding member 65 to move vertically with relationto the carrier. In order to maintain free movement of the eyelets 61along the guide rods 52, a collar 69 of felt or like material may beprovided on each of the guide rods, which collar may be saturated with alubricant and arranged to slide on the rods to lubricate and clean theguide rods. Y

The means for retaining copy sheets on the front face of the copyholdingplate 65 may be of substantially the same construction as shown inPatentNo. 1,719,422 granted July 2, 1929. Referring particularly toFigs. 1, 2 and 4, it maybe seen that this construction includes a bail15 extending horizontally across the ltop portion of the copyholdingplate 65, and the inwardly extending ends of this bail are received inslots provided in opposite end portions of a bracket 16 extending alongthe upper edge portion of the plate 65. An arm 18 is secured in achannel in each end of the bail 15, and springs 19 are provided betweeneach of the arms 18 vand the top portion of the bracket 16 to normally,press the topY of the bail inwardly toward the copyholding plate. Aplurality of rubber rings 8 are arranged on the horizontal portion ofthe bail 15. Thus, a copy sheet, or stenographers note book may beplaced beneath the rubber rings 80 and securely clamped against theplate 65 by the force of the springs 19. When it is desired to insert orremove material to be copied, the bail 'l5 may be swung forward to aposition wherein the arms 18 engage the rear surface of the bracket 16and the lower ends of the springs 19 are thus moved across the pivotalaxis of the bail 15 to retain the bail in this forward releasedposition.

Means are also provided for holding transcribed copy sheets in a turnedposition over top of the copy carrying plate 65. This means in thepresent instance is shown as a spiral contractile spring 82 extendingacross the top of the horizontal portion of the bracket 16. The ends ofthe spring 92 are attached to the respective end por-- tions of thebracket 16, and the spring is provided with a certain amount of tensionso that sheets after they are copied may be placed beneath the spring tobe held thereby in a turned position over the top of the copy carryingmember 65.

The means for controlling the upward and downward movement of the copycarrying plate 65 with relation to the carrier includes mechanismcarried in part by the carrier and in part by the stationary baseymembers. The portion of this mechanism carried by the stationary basemembers includes a forwardly extending lever 85 which is pivotallymounted at 86 to an upstanding portion of the forwardly extending basemember as shown in Figs. 1 and 2. A handle 88 is mounted at the forwardend of the lever 85, and this handle may be adjusted along the lever 85to the desired position with relation to a typewriting machine T. Theadjusted position of the handle 88 on the lever 85 may be retained bytightening a clamping screw 89 provided on the handle.

The rear portion of the lever 85 is bent inward and is provided with areduced semi-circular end forming a ball and socket type connection witha bifurcated member 92 carried by the end of an arm 93. The arm 93 ispivotally mounted at 94 to an upstanding portion on the rear base memberI as shown in Fig. 2. It will be noted thatJ the ball and socketconnection between the lever 85 and the arm 93 is normally positioneddirectly above the pivot screw |6 connecting the twol base members` l0and H; Accordingly, the Ylever merely pivots about its connection withthe arm 93 when the forwardly extending base member I is folded againstthe rear base meme ber |0.

The portion of the mechanism for controlling the upwardA and downwardmovement of the copi/holding member which is mounted on the carrier maybe generally similar to that disclosed in Patent No. 1,837,027 issuedDecember 15, 1931. This mechanism includes a lifting rod 91 fixedlysecured at 98 to the upper bracket member 16 on the copyholding plate65, and the lower end of the rod 91 is retained against displacementlaterally by an extension 99 on the lower guide bracket 66 at the bottomof the copyholding plate. The extension 99 passes through an elongatedvertical slot |0| in the carrier cover plate 50 and the upper end of therod 91 passes through an opening'in the top flange portion of the rearcarrier plate 20.

The upward and downward movement of the copyholding plate is effectedthrough a control rod |03 `mounted for longitudinal movement on thecarrier. The upper end of the control rod |03 passes through an openingin the top ilange of the carrier plate 20, and the lower end of thecontrol rod is retained against lateral displacement by a guide bracket|04 secured to the carrier plate 20 to partially embrace the rod |03 asshown in Fig, 5. In order to provide a substantially noiseless andfrictionless guide for the upper ends of the rods 91 and |03, a liberplate |05 is secured to the lower surface cf the ange at the upper endof the carrier plate 20 as shown in Figs. 2, 3 and 5. This ber plate isprovided with bearing openings receiving each of the rods 91 and |03,and the metal of the carrier plate ilange is cut away around thesebearing openings to be out of contact with the rods.

The control rod |03 is moved either upward or downward from itsillustrated position to control movements of the copyholding plate 65,and for this purpose an interconnecting means is provided in the form ofa link ||0 pivotally connected at to the intermediate portion of the arm93 on the base member I0, and the upper end of the link is operativelyconnected to the lower end of the rod |03 when the carrier is in itsraised operative position. Referring to Figs. 2 and '7, it may be seenthat the connection between the upper end of the link ||0 and the rod|03 comprises a clip ||4 attached by a screw ||5 to the lower end of therod, and the clip carries a shouldered screw ||6 threaded into anenlarged retaining washer ||1. 'I'he intermediate portion of the screw||6 passes through an elongated slot ||8 extending substantially theentire length of the link ||0, and the upper Vend of the slot ||8extends laterally toward the rod |93 to provide shouldered portionsdisposed above andbelow the body of the screw 6 when the carrier is inits raised operative position as shown in Fig. 2 for example. A leafspring member |20 is secured by the screw I5 in a position toresiliently hold the upper end of the link I0 in a position wherein theshoulders formed by the upper end of the slot ||8 are disposed above andbelow the screw |6 and thereby operatively connect the lever 93 with thecontrol rod |03.

It will now be clear that a manual depression of the handle 88 willcause an upward movement of the control rod |03 through the arm 93 andlink ||0. This upward movement of the rod |03 istransmitted to thecopyholder rod 91 through a lifting clutch member |25 which is formed ofa rigid piece -of channel-shaped metal having a slotted end portionwhich straddles the control rod |03 as shown in Fig. 6. A pin |26 iscarried by the rod |03 directly beneath the lifting clutch member |25,and a retaining pin |21 is also carried by the rod just above the clutchmember |25.

The copyholder rod 91 extends througha rectangular aperture in thelifting clutch member |25, and clutch jaws |30 are mounted in thisrectangular aperture to engage opposite sides of the rod 91 Each of thejaws |30 comprisesametal casing having a non-metallic lining or fillerof the type specifically disclosed in Patent No. 1,837,027. Thus, whenthe control rod |03 is moved upward by a depression of the handle 88,the lifting clutch member |25 receives a slight angular movementcaus-ing the clutch jaws |30 to grip the copyholder rod 91 so that thecopyholding plate 65 is moved upward by the continued upward movement ofthe rod |03.

This upward movement of the copyholding plate 65 moves the copy sheetpast the line indicator 55, and in vorder that this movement may beadjusted to accord with dierent extents of line spacing on various copysheets, an adjustable stop is provided Vfor limiting the operation ofthe lever 85. Referring to Figs. 1, 2, and 8, it may be seen that thisadjustable stop is mounted on a bracket |34 secured to the rear portionof the base member Il. The bracket |34 extends upward 'at the side ofthe rearward end of the lever 85, and a stop member |35 is mounted forvertical adjustment on the bracket' |34. The upper end of the stopmember |35 is bent inward and is provided with a cushioned stop contact|36 which is positioned to be engaged by the rearward end of the leverY85 when the handle 88 is moved downward. The desired position ofadjustment of the stop member |35 may be retained by a clamping'screw|31 which passes through a vertically disposed slot in the bracket |34and is threaded into the stop member |35. Thus, the position of the stopmember |35 may be adjusted to aiord an extent of movement of the lever85 which will result in the desired extent of line spacing movement ofthe copysheet with respect to the line nder 55.

A' returning spring |40 is provided between the arm 93 and the rear basemember I0 as shown in Fig. 2. This spring acts to return the lever 85,armr93 and rod |03 to their normal'positions when the downward pressureon the handle 88 is removed. During this downward return movement of therod |03, the end of the lifting clutch member |25which is connected tothe rod |03 is moved downward toward' a straightened position whichreleases the clamping engagement of the clutch jaws '|30 with thecopyholder rod 91. Thus, the return downward movement of the rod |03does'not cause Va corresponding downward movement of the copyholdingmember through the rod 91.

A releasable 'holding clutch mechanism is provided'for normallyretaining the copyholder in the position to which itis raised throughthe liftingclutch memberv |25. This holding mechanism com-prises avholding clutch member '|42 which is generally similar to the liftingclutch member 25. One end of the member1|42 is bifurcated to straddle`the control rod-|03 inthe same manner as the member |25 and the otherend `is likewise provided -with a rectangular shapedapertureinwhich-apair ofl clutch jaws Vrod '91.

extendingiportion of a bracket |45 which is secured at |46 to thecarrier plate 20. A contractile spring |41 extends between the bracket|45 and the intermediate portion of the clutch-member |42 to normallyhold it in a position wherein the clutch jawsv |43 'are in clampingengagement with the rod 91 to preventvdownward movement thereof.However, when the rod 91 is moved upward through the lifting clutchmember |25, the clutch member |42 receives a slight pivotal movementabout the bracket |45 until the clutch jaws |43 do not effectivelyengage the rod 91 and thus permit the rod 91 to move upward relativethereto. When the upward force on the rod 91 is removed, the tendency ofthe copyholder to move downward causes the clutch jaws |43 to againengage and hold the rod4 91.

When it is desired to lower the copyholding plate 65 on the carrier, thehandle B8 may be raised from its normal position to pull downward on theclutch control rod |03. This downward movement of the rod |03 causes thepin |26 to engage the holding clutch member |42 and move it toward ahorizontal position against the force of the spring |41. This movementof the member |42 releases the normal gripping engagement of the clutchjaws |43 with the rod 91 thereby permitting the copyholding plate 65 tomove downward by gravity to its normal or first-line copying positionwith respect to the carrier.

A retarding mechanism is provided in the present copyholder in order toprevent the copyholding p1ate'65 from gaining undue momentum in itsdownward movement. This retarding means in the present instancecomprises a retarding clutch member |5| having clutch jaws |52 carriedthereby inA contact with opposite sides of the rod'91. lOne'end of theretarding member |5| is mounted at |53 to the lower side of the topangeportion of'the carrier plate 20, and the other end of the member |5|carries a threaded rod |54 extending upward through an aperture in theflange of'the carrier plate. An expansion spring |55 is provided on thethreaded rod |54 between the retarding member |5| and the flange ofthe-carrier plate 20 and a knurled adjusting nut4 |56 is threaded on theupper end of the rod 54- to normally engage the upper surface of thiscarrier plate ilange The slight angular disposition of the member |5|causes a slight gripping action Ibetweenvthe jaws 52 and the rod 91 toretard thedownward movement of the copyholding plate L65, and the extentof this retarding action may bevaried by turning the nut |56 in onedirection'or the other to accordingly vary the angular disposition ofthe member 5|.

vThe copyholding plate 65 with the copy sheets or other' transcribing.material attached thereto is thus retarded in a downward movement tonormal position on the carrier, and shock ab sorbing means are providedto arrest the copy carrying plate in its normal position with a minimumof noise-and shock. Thus as may be seen in. Figs. 2 and 4, a coiledexpansion spring |58 is placed around the bottom portion of each ofthe.` guide rods 52. The lower ends of these springs 58' rest on thelower ange of the carrier plate 20, and as the copyholdng plate 65reaches its lowermost normalposition, the upper ends of the springs |58are engaged by the lower portion of the bracket 66 on the copyholdingplate as shown in'Fig. 4 to resiliently arrest the downward movement ofthe copyholding plate with a minimum of noise and shock. l

It will now be understood that when the carrier is in its raisedoperative position on the guide posts 22, the copy carrying plate 65 maybe moved relative thereto intermittently in an upward direction bydepressing the handle 88 and may beA returned downward to its normalposition by lifting the handle. In order to control this movement of thecopyholding plate on the carrier, the connecting link IIO has beenarranged to transmit both upward and downward movement from the arm 93to the rod |03 when the carrier is in its raised operative position.Accordingly, the operative connection between the link I and the rod |03must be interrupted when it is desired to move the carrier to' itslowered collapsed position with relation to the base. In accordance withthe present invention, means are provided for automatically interruptingthis operative connection between the link IIIJ'and the rod |03 when thelatch members 26 are operated to a released position enabling thecarrier to be lowered to its collapsed position. Referring to Figs. 2and 7, a slide |64 lis mounted for horizontal movement on the inner4side of the carrier plate 20 by headed rivets |65 passing throughrespective slots in the slide |64. One end of the slide |64 is bentlaterally to coact with the edge of the link I I0 but is normally heldlout of contact therewith by a contractile spring I 66 extending betweenthe slide |64 and a pin |61 secured to the carrier plate 20. The outerportion of the slide |64 extends vupward and Vis provided with alaterally bent end whichnormally engagesthe edge of the lower portion ofthe left-hand releasable latch member 26. Thus, when the latch members26 are moved inward out of engagement with the shoulders 31 ofthe guideposts 22 by depressing the linger pieces 40 of the latch releasinglevers, the left hand latch 26 moves the slide |64 horizontally toengage the edge ofthe link I'IIJ and causes a movement of the upper endof the link toward the rod |03 against the force ofthe spring |20. Thismovement of .the upper end of the link IIO positions the verticalportion of the slot II8 beneath the body portion of the connecting screwI6 so that the carrier'may be moved downward along the guide post 22with the screw vI I6 moving in the vertical portion of the slot II8.

In this manner, the link |I0 which normallyconnects the arm 93 with therod |03 for movement in either direction when the carrier -is in itsraised operative position is automatically disconnected by operation ofthe releasablev latch mechanism to permit the carrier to be readilylowered to its collapsed position. When it is desired to again raise thecarrier to its operative position, the screw I I6 slides in the slot I|8until the carrier is latched in its operative position, whereupon thespring I 20 moves the upper end of the link IIO back to its illustratedposition which operatively connects the arm 93 and rod In order to placethe present copyholder in its fully collapsed condition, it is not onlynecessary to move the carrier downward with relation to the base, but itis also necessary to have the copyholding member in its normal positionwithrelation to the carrier. Accordingly, means are provided inaccordance with the present invention for automatically returning thecopyholding member to its normal or lowermost position with relation tothe carrier when the carrier is released for movement to its collapsedposition with relation to the base.

Referring to Figs. 2 and 6 a lever |10 is pivotally mounted at itscentral portion on the inner surface of the carrier plate 20 by a headedrivet I1I. One end of this lever |10 is bent laterally to normallyengage the upper edge of the inner end portion of the right-hand latchreleasing lever 33. The other end of the lever |10 is also bentlaterally to extend above the bifurcated end of the holding clutchmember' |42. Thus, when the latches 26 are released to permit downwardmovement of the carrier to its collapsed position, the lever |10 isrocked about its pivot by the releasing movement of the right-hand latchreleasing lever tothereby move the holding clutch member I 42 toward itshorizontal position. This movement of the member |42 releases theclamping engagement of the jaws |43 with' the rod 91 and permits thecopyholding plate to move downward to its normal position 'as previouslydescribed.

The present collapsible copyholder may if desired be secured permanentlyin the usual manner to the supporting surface of a folding cabinet of atypewriter desk. However, means are provided which cooperate with atypewriting ma-l chine, such as T shown in Fig. 1, to releasably retainthe copyholderin position against accidental displacement, therebymaking it unnecessary to `permanently secure the copyholder to thesupporting surface.

` The means shown in the present instance for retaining the forwardlyextending base member I I is fully disclosed in Patent No. 2,155,246issued April 18, 1939. This retaining means may be generally describedas comprising a carrier |15 mounted for vertical movement in a slot |16in the base member II. ing arm |18 is pivotally mounted on the carrier|15 for movement between its position shown in Fig. 8 and a collapsedposition against the inside surface of the base member II. Spring means,not shown in the present drawings, are provided to act upward on thecarrier |15 and to hold'the.

arm |18 in engagement with the lower edge of the typewriter side plate.The carrier |15 is so arranged that any force tending to raise the basemember II from its supported surface is resisted by the engagement ofthe arm |18 with the typewriting' machine to cause a binding actionbetween the carrier and the base member,` I I. This retainingk means maybe readily released by a downward pressure on the carrier member |15,and it is arranged to cooperate equally well with different typewritingmachines regardless of thel distance between the lower edge of the sideplate and the supporting surface.

Means are also provided for retaining the lefthand rear portion of thecopyholder against displacement with relation to the typewritingmachine. This retaining means may if desired, be the same as thatprovided on the base member II, but in the present instance a specicallydifferent means has been shown. Referring to Figs. 2 and 8, it may beseen that a rubber covered retaining'arm |80 is mounted on an adjustableslide member ISI for pivotal movement thereon between a forwardlyextending position as shown and a folded position along the base memberI0. The slide |8I is mounted for vertical adjustment along an upwardextension |82 on the base 'member It, and the arm lso is normallypositioned in A rubber covered retain- Animproved-copyholder hasthusbeen pro-- videcljwhioh' is comparatively simple and inexpensivetomanufaoture and yetv highly effective and reliable in use. Aparticular feature of the present copyholder is the arrangement of thecopyholding member on a carrier which may be movedwith relation to itsbase between a raised operativev position4 and a lowered collapsedposition: This feature involves'the provision of improvedmech'anismforcontrolling the movements ofthecopyholding member. with relation to thecarrier, which mechanism isjointly carried by the base` .andthe carrierwithinterconnecting means arranged. to` automatically establish anoperative connection between the controllingmechanism on thebaseand'thecontrolling mechanism on thesoarrier. whenithe carrierreaches its raised operative position and' having means forautomatically interrupting this operative connection'when the. carrier;is released for movement to itslowered'` collapsed. position..

Another feature of the present copyholder is the provision'oi mea-nsforautomatically returning'fthe'copyholding member to -itsnormal posi'-tioncwith relation to the carrier as, thev carrier is moved Ftoitscollapsed position; TheseVV features cooperate'to provide a.copyholder which ymay be easily and `quickly changed lfroma conditionaffording normal operation to a collapsed condition permitting vit to behoused together with a typewriting machine'in the' folding compartmentof aV typewriter desk.
